To all ttf/nay. concern: i' Beit known that we, JAMES A. SwEARER, a citizenof the United States, residing at Beaver, in the county of Beaver and-Staterof f Pennsylvania, 'and ,CHARLES E. TOYNBEE, a citizen of the United States, residing at M013 gantown, in thecounty of Monongalia and State of I/Vest Virginia, have invented or discovered' new and useful Imrovements in Apparatufor Making Wiredass, o'f which the following is a specification. i

The figure shows in longitudinal section one form of apparatusfor making wirefglass. v- Our invention relates to the manufacture of glass with a 'wire netting or trellis embedded therein.

' It has been proposed to start the first layer with the Wire embedded in the top thereof,

and then pour and 'roll'the secondy layer on the irst'as' soon as the leading roll has passed sufiicic'ntlyfar to permit the second pouring. The trellis'isembedded in the first layer simultaneousiy with its formation and while too fluid to support the trellis Without its becoming embedded. the first layer in substantially this condition w l the second layer is applied, the trellis being between thetwo layers of glass before either has become set or Ychilled to any appreciable degree.

In using our apparatus the trellis` is not applied until theA first layer will support it. Vi e embed the trellis in the under si e of the upper layer and 'apply the'two to the-set or -chilled surface of the first layer. v

In/'the drawing, 1 represents the casting bed; 2 the leading roll; and 3,'the finishing roll.

4 is a chute for the trellis 5 and terminates a short distance behind the finishing roll 3.

6 and 7 are the usual knives or guides for the melted glass.

The operation'is as follows: .A batch of glass is poured behind the leading roll 2 at 8 right, a sheet o'r layer 9 of glass being formed. A second pouring of glass is made at 10 behind the roll 3.-v When the advanced end of the sheet 9 reaches the second pouring the trellis 5 is introduced in front of the pouring and the roll 3 rolls out on toplof the sheet 9 a second layer with the trellis embedded in the latter. The

.second lager with the trellis is not applied )until the rst layer is sufficiently hard to per- Init 'the trellis'to lie on its surface without being embedded therein or until after the first layer has been completed.

It is clear that the table may be stationary while the rolls with their knives and the chute may be movable.` It is to be noted that by our apparatus, the treliis is not exposed to the oxidizing aotion of the air after it has been assembled with the glass, asis the case where the trellis is embedded in the first layer by the leading roll. 4 When the trellis is thus embedded with its upper incandescent surface exposed to the air in the space. between the leading roll and the second pouring of glass, its upper surface is dark with scale and its lite is thermore, during the interval rom the time the embed ded trellis leaves the iirstroll until it arrives at the second pouring, the trellis becomes melted and as itgenters theq secondv pouring the melted metal smears the glass, rendering it unsightlyand unmarketable. llf the second pouring is made before the fi rst layer is suiiiciently liard, as is d one when the second pouring is made as soon as possible after the leading roll has passed, the trellis will not be rigidly held in the first layer when the second layer 'is applied, the result. i being that thetrellisis distorted and its level l disturbed. l By stating that the first sheetmust be'- i come sufficiently hard to support the trellis beforethe latter is applied thereon, it is not to i slight degree be in the said sheet. AIt 'is essential only' that the first sheet should be sufficiently bard to hold the trellis from becoming irregularly seated.

Having described claim is :e-

sheets, a roll for sheet, a second roll behind the first named roll for rolling the upper a trellis chute between t sufficiently far behind the first roll to feed the trellis upon the lower portion. of sheet after it has become hard enough to support the same, the chute being also arrangedA so as to direct the trellis into the thev up er po'rtion of the sheet at such a place as to e covered bythe saidupper portion be understood that the trellis may not to a.-

lower part of the glass from which is formed burned out and its utility im aired. Fursubstantially as soon as it contacts with the said .lower portion.'
